CAT 3406E (Prefix 5DS or 1LW) Fault Code: 66 PID: 40 SPN: FMI: 5 Auxiliary Output #02 current low

The ECM detects the following conditions:

There is a low current condition (open circuit) in auxiliary output 02.

The solenoid that is currently enabled will remain in the ON position until neutral is detected. Then manual operation occurs until the system powers down. Manual operation is defined as both solenoids OFF.

Probable Causes:

1) ECM Connector/harness
2) Shift solenoid failure
3) Shift solenoid relay
4) Wiring between shift solenoid and ECM
5) Gear ratios are programmed incorrectly in the ECM
